Heat Treated NiP–SiC Composite Coatings: Elaboration and Tribocorrosion Behaviour in NaCl Solution [PDF]

, 2009
Tribocorrosion behaviour of heat-treated NiP and NiP–SiC composite coatings was investigated in a 0.6 M NaCl solution. The tribocorrosion tests were performed in a linear sliding tribometer with an electrochemical cell interface.

Decoupling retrieval quality from generative reasoning: A multi-dimensional benchmark of RAG architectures [PDF]

EPJ Web of Conferences
Traditional search engine returns ranked lists for humans to interpret. Retrieval Augmented Generation pipelines go further, feeding retrieved context directly into large language models to synthesize knowledge rather than simply surface it.

Ablation-Immune Thermal Armor Via Microstructural-Compatibility Design for Extreme Thermal Conditions. [PDF]

Adv Sci (Weinh)
This study unveils a microstructural‐compatibility design strategy that integrates reactive melt infiltration with plasma spraying to fabricate carbon fiber‐reinforced ZrC‐SiC composites. The deliberate incorporation of SiC into the ZrC coating releases heat accumulation, suppresses detrimental lamellar ZrO2 formation, and reduces residual stress. This

Oxidative/Nitrosative Stress and Brain Involvement in Sepsis: A Relationship Supported by Immunohistochemistry

Medicina
Background and Objectives: A large amount of recent evidence suggests that cellular inability to consume oxygen could play a notable part in promoting sepsis as a consequence of mitochondrial dysfunction and oxidative stress.

Fabrication of SiC/SiC composites by means of in situ crystallization of SiC fibers [PDF]

Journal of Nuclear Materials, 2011
A novel challenge, the in situ crystallization of Pre-SiC reinforced-fiber during the fabrication of SiC/SiC composites, has been made for cost effectiveness. Constituent parts of each fabricated material with various manufacturing conditions were assessed by microscopic observation.

Thermochemical Core-Shell Architecturing of Si-SWCNT Composites for High-Performance Li-Ion Battery Anodes. [PDF]

Adv Sci (Weinh)
A thermochemically engineered core–shell Si architecture is developed through the controlled evolution of a SWCNT‐coated Mg2Si precursor. The process simultaneously generates a nanoporous Si shell for strain accommodation and Li+ transport, a chemically anchored SiC interfacial layer for robust mechanical and electrical coupling, and a Mg‐containing Si
